Our product

 

The primary jaw crusher is mainly composed of a frame, an eccentric shaft, a large pulley, a flywheel, a side guard plate, a toggle plate, a toggle plate back seat, a gap adjustment screw, a reset spring, a fixed jaw plate and a movable jaw plate.

1. Withstand strong impact

The split welded cast steel frame of the jaw crusher for stone, heavy eccentric shaft and bearing, have strong impact resistance;
A heavy guard plate is installed above the movable jaw.

2. High-quality material finishing

The jaw plate and side guard plate of the jaw stone crusher machine are made of high manganese steel, the toggle plate is made of gray cast iron, and the eccentric shaft is made of high-strength forged steel. They are made after multiple precision machining, heat treatment and flaw detection.

3. Overload protection mechanism

When the mechanical jaw crusher is working, materials that exceed its crushing capacity may enter.

These materials will have an adverse effect on the operation of the jaw crusher and may even damage the crusher.

At this time, the toggle plate will break by itself to protect the crusher equipment from damage.

4. Easy to operate and maintain

The portable jaw rock crusher has a gasket-type discharge adjustment device and a centralized lubrication system, which is easy to operate and maintain;

The jaw plate is a symmetrical structure, which can be used up and down after wear, which increases the service life and saves replacement costs.

1. The bearing temperature exceeds the allowable temperature, and the return oil temperature exceeds 60℃
The reason may be that the bearing bush is pressed too tightly. The bushing can be adjusted with a gasket. Or the lubricating oil is insufficient, the lubricating oil path is blocked, and the lubricating oil is dirty. At this time, the amount of lubricating oil needs to be increased, the oil pipe is cleaned, and the lubricating oil is replaced.
2. The oil flow indicator shows that the oil is cut off. It may be a problem with the oil pump. The oil pump should be repaired or replaced.
In winter, the oil temperature is too low to cause oil cut-off. The oil can be heated.
